The Rayburn Royal OF7 was introduced in the late 1960s as the oil fired version of the Royal SF. It was initially just known as the Oil-fired Rayburn Royal. Intended for continually burning, to give cooking and domestic hot water, it was available with both right hand and left hand ovens. The burner was a vapourising sleeve type, using 28 second kerosene, to produce heat for the oven and domestic hot water. It was also available as a non boiler model, for cooking only.
Early models had a single, one-piece insulating lid, later changed to the twin pattern.
The heat level was adjusted by use of the dial on the oil control valve, which was usually mounted on the side of the appliance. This increased or decreased the fuel flow rate to the burner; there being a defined minimum and maximum flow rate for the correct function of the appliance.
The maximum heat to the domestic hot water was 7000BTU/Hr ( 2KW) obtained when the control was set on high setting, giving the highest oven temperature. Circulation to the hot water cylinder ( direct or indirect ) was by gravity.
Optional extras included a splash-plate and a plate-rack.
In about 1988, the left hand oven option was dropped in favour of the standardised r.h. model.
From the mid-90's the product became known as the 208K, or 200K for the non-boiler version, incorporating polished insulating covers and slam-catch doors. Production of these models continues.
